Hi;
I have the following:
mysql> select * from categoriesProducts as c inner join relationshipProducts
as r on c.ID = r.Child inner join categoriesProducts as p on r.Parent = p.ID
where p.Category = prodCat2;
ERROR 1054 (42S22): Unknown column 'prodCat2' in 'where clause'

So I'm at a loss. No, 'prodCat2' isn't a column, but I don't understand how
I specified that in my query. Please advise.
TIA,
Victor
You didn't quote prodCat2 in the query, so it was assuming you were
referring to the column name. Try:
select * from categoriesProducts as c inner join relationshipProducts
as r on c.ID = r.Child inner join categoriesProducts as p on r.Parent = p.ID
where p.Category = 'prodCat2';
